rails, and has for'its object toprovide an exceedingly simple andeffective device of this character, whereby a locking plate, the spikesand the, rail are locked together so that no one of them can be removedby vibration'or thelike without the other.

Another object of the device is to provide means for preventing theslipping or lateral movement of the rails.

With these endsin view, this invention consists "in the details ofconstruction and combination of elements hereinafter set forth and thenspecifically designated by the claims. Y

In order that those skilled in the art to which this inventionappertains may understand how to make and use the same, I will describeits construction in detail, referring by letter to the accompanyingdrawing forming a part of this specification, in which- Figure 1 is alongitudinal sectional view of a tie, rail and the locking plate, thespikes being left in elevation" Fig. 2, is a plan view thereof. Fig. 3,is a plan view of the locking plate. Fig. 4, is a view similar to Fig. 1of a slightly modified form of my improvement. Fig. 5, is a plan viewthereof, and Fig. 6, is a plan view of the modified form of the lockingplate showing its shape before the ends are bent up.

In carrying out my invention as here embodied, A represents atie, whichmay be of the usual or any preferred form and preferably constructed ofwood, and B is the rail used in constructing railway tracks. In the tieA maybe formed a groove C, in which is placed the locking plate D,beneath the base E of the rail. The locking plate D is formed of a stripof metallic material, the ends of which are beveled from the under sidetoward the ends, as indicated by F and having two elongated slots Gformed in the body portion thereof, the' space between said slots beinapproximately the width of the rail base Through the elongated slots Gpass the spikes H, provided at the upper end of the shank I with a head-J, from which projects arail engaging portion K, which has an inclinedlower face to conform to the configuration of the upper face of the:rail base E. The point L ofthe spike is tapered as shown, and a taperedenlargement M is provided at the rear upper half of-the shank, and inthis is formed a notch N adapted to engage the locking plate D when therail engaging base.

In practice, when the road is first being laid, grooves may be formed inthe ties, in which will rest the locking plates D, but when laying a newtie in place of an old one said tie may first be laid and then thelooking plate D driven into the tie beneath the rail. until theelongated slots G rest one portion is resting upon the rail upon oneside and one upon the other of the rail base. One of the spikes H isthen driven into the tie through the elongated slot G, the taperingportion N of said spike moving the lo'ckin plate D about until it haspassed through the slot, then said looking plate may be moved to oneside until it enters the notch N in the spike. The opposite spike isthen driven through the opposite elongated slot into the tie, and indoing so it compresses the wood so as to allow it to pass through theslot until the notch is opposite said slot, at which time the wood inthetie causes said slot. to engage. the

locking plate, when all the parts will besecurely locked together, andalthough the rail were to move up and down a considerable distance itwill not have a lateral movement which would spread the rails, so thatit is not necessary to have the spikes secure within the tie to preventthe spreading of the rails.

In my modified form of device as shown 7 in Figs. 4, 5 and 6, I formextensions 0 with the ends of the locking plate D, and when the spikesare in position these extensions are bent upward and over the top of thespikes so that when any weight is brought to bear upon the locking plateI),

such as a train passing over the rails, as the body of said plate ismoved downward .the ends of said plate will naturally bend upward and itwould ordinarily be thought that the spikes would be drawn upward andout of the tie, but this is not the case, because as the body of thelocking plate moves (Jr are brought closer to the base of the rail,

thus drawing the spikes closer to the base of the rail, causing saidspikes to be drawn to some certain angle, thus preventing them frombeing withdrawn. The extensions 0 are only used as an extra precautionto prevent the spikes from being Withdrawn from the ties by vibration iffor any reason whatsoever the notches in thespikes become 'disen agedfrom the locking plate.

f course I do not wish to be limited to the exact details ofconstruction here shown, as these may be varied within the limits of theappended claims'without departing from the spirit of my invention.

Having thus fully described my invention what I claim as new and useful,is-

1. The combination with a tie and a rail disposed thereon, of meansto'secure said rail to said tie, comprising a locking plate having slotstherein and having its ends beveled from the inside upward toward theouter edges, and spikes provided with means for engaging the lockinplate when said spikes have been directe through the slots and into thetie.

2. The combination with a tie and a rail disposed thereon, I of means tosecure said rail to said tie, comprisinga locking plate havin'slotstherein and having its ends beveled rom the inside upward towardthe outer edges, and spikes having notches formed in the real portionthereof adapted to engage the locking plate when directed through theslots and into the tie.

3; The combination with a tie and a rail disposed thereon, of means tosecure said rail to said tie, comprising a locking plate having slotstherein and having its ends beveled from the inside upward toward theouter edges, and spikes having rail engaging portions and taperingengagements provided with notches, said notches adapted to engage thelocking plate when the spikes are directed through the slots and intothe tie.

at, The combination with a tie and a rail disposed thereon, of means tosecure said rail to said tie, comprising a locking plate having slotstherein and having its ends beveled from the inside upward towardtheouter edges, and spikes, the shanks of which are provided'with headshaving rail engag ing portions projecting therefrom, the lower ends ofthe shanks being ta ered, and wedge shaped engagements provi ed" withnotches adapted to engage the locking plate when
